Regions: Crowsnest North, Crowsnest South.

Continually assess the wind effect and new snow amounts as you move through terrain. Wind and storm slabs will likely remain reactive to rider traffic.

Wind and storm slab reactivity could increase if the sun comes out.

Confidence

Moderate

Avalanche Summary

Ski cutting continues to produce small wind slabs and dry loose avalanches.

No other significant avalanches reported in the past few days.

Snowpack Summary

Up to 20 cm of new snow has fallen past 24 hours. At higher elevations this sits over extremely wind affected surfaces including large sastrugi. Many west facing alpine areas may not hold new snow and instead be stripped back to hard surfaces.

A melt-freeze crust with facets above, sits 50 to 120 cm deep. It has not produced any avalanches.

The mid to lower snowpack is considered well bonded at this point. Currently we are not seeing the same basal weak layers and reactivity that many of the neighboring regions are experiencing this season.

Weather Summary

Friday Night

Mostly cloudy with a few centimeters of new snow possible. Moderate to strong westerly winds and a low of -11°C at 2000 m.

Saturday

Sunny in the morning with increasing cloud and flurries in the afternoon bringing trace amounts of new snow. Light winds increasing to moderate easterly in the afternoon. High of -8°C at 2000 m.

Sunday

Mostly cloudy with up to 5cm of new snow expected. Strong easterly winds and a high of -12°C at 2000 m.

Monday

A mix of sun and cloud with the possibility of light flurries bringing trace amounts of new snow. Light southwest winds and a high of -9°C at 2000 m.

Terrain and Travel Advice

  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Be alert to conditions that change with elevation and sun exposure.

Avalanche Problems

Storm Slabs

New snow has formed a storm slab that could still be reactive to rider traffic. The largest and most reactive slabs will likely be found on east aspects.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Possible

Expected Size: 1 - 2
